Holding Tool variomatic drive belt pulley SIP

Holding tool for blocking the pulley on the crankshaft

Whether changing the V-belt, installing the sport vario or simply replacing worn vario rollers - the fact is, the pulley has to come down. Since not everyone has an impact wrench and it is not exactly gentle on the crankshaft stub, we recommend using the special SIP variator holding tool. What are the advantages of the holding tool for the variator?

• Needed to fix / loosen the variator nut
• Easy handling
• Practical for workshop and on the road

The holding tool is needed to loosen and fix the Vario nut. To do this, the tool is placed on the pulley with the two retaining lugs and screwed to the motor housing by means of the bushing and the screw. Now you can easily loosen/tighten the nut with a ratchet or torque spanner. No workshop should be without this tool, but it is also advisable to have the holding tool with you at all times when touring. Anyone who has ever tried to change a broken V-belt in the middle of nowhere without a holding tool will know how important the small holding tool can be for the Vario.

Conclusion: Useful helper, not only for occasional mechanics but also for workshops and touring riders.

The right accessories - our SIP TIP:

• To complete the range of special tools, the BU5428 clutch retaining tool is a must.
• For proper assembly of the Vario nut, we recommend observing the tightening torques. A suitable torque spanner is required for this

Assembly note: If you use the retaining tool on your HPE engine, you have to modify it a little bit with a file or angle grinder. One corner of the retaining arm must be modified slightly, otherwise the tool will hit the fan blades of the pulley.
